• Summary: add support for a dpkg diversions control file

• Required skills:

  • Familiarity with dpkg
  • C

• Description: To do diversion in its currently required to do them via dpkg-divert in the package maintainer scripts (postinst, preinst). This makes it more difficult to scan for diversions in a programmatic way (useful for e.g. automatic checking of conflicts or apps like command-not-found). A declarative way should also make diverts more robust.
